After a few dozen flights my C186 started to toilet bowl. I corrected this problem with the hover debug precedure as shown. It hovers and flies stable now. Backwards manoeuvers all no problem.
Hello, you seem the most knowledgeable in all of these RC era helicopters. I am having an issue with one of the MD 500 helicopters. I have two of them. The styles shouldn’t have mattered, but I even went as far as changing the red Coast Guard model out for a sand Camel Fage model and back vice versa, the issue that I’m having is this once in a while when I’m flying one of the MD 500 helicopters, the five blades will fold up on each other. The rotorhead stop spinning and it falls out of the sky by folds up as the five blades fold back on themselves and the rotorhead stops spinning , and obviously the helicopter will fall out of the sky. I have gotten lucky twice. I was only a few feet off the ground and landed in some of Florida’s nicest thickest grass and there was no incident one of the other times that I was flying ahead and landed on the concrete. Needless to say, the landing gear buckled under the load, and the company no longer just sells landing gear through the bank website. They now sell the entire fuselage kit, and that was painful to say the least to have to buy all of those parts just to get one set of landing gear happens with red rotor blades with yellow rotor blades on one of my models Z fold up on themselves and the helicopter falls out of the sky. If you don’t understand what fold up means take with your finger and push all of the blades back till they will no longer go backwards anymore on the rotor grips and that is what I mean but that occurs underload underlying conditions. It’s as if the rotor continues to move counterclockwise and all of the rotor blades stop spinning and fold onto themselves. Can you please help?
I would be happy to help. Can you post a video of the problem? I mean I read and get what you say, but its hard to diagnose it as its very strange. A video may her. What I can assume is that the pitch is not set correctly or something much simpler, the blade grip screws are on too loose. A video will help. Thanks.
Strange that it was secret especially if it helped the heli fly better. Good Job letting us all know. Is debug mode still the left trim button even if you fly mode 1 ?
@@winstonsmith7801 it’s really not that they intentionally didn’t want to tell us. I think they are a small company and slowly they are addressing all these needs.
If I remove the helicopter battery or the transmitter batteries, will I lose the trim settings and have to perform a recalibration again/over? Thanks much!
@@jeffkraus1457 if you setup the gyro through the gyro debugging procedure where you get a level hover and save the settings no you do not lose the settings. However, if you just trim the heli without going through the debugging setup you will lose the trim setting.
@@Flight6677 thanks a lot 🙂. To be a bit more clear: If i use one radio for C186 and C123 do I need to recalibrate every time i switch model or just bind and go ? I suppose the two models have different setting or not ? Thanks again in advance for your kind reply
@@dgiky no you don’t. You can do the level hover setting for each heli independently and each flight control unit will save its own settings. But if you didn’t go through this internal setting you will need to reset trim each time. As I show in the video the procedure is also called debugging. It’s nothing more than entering gyro programming mode.
Thats not what the down trim does. All it does is turn off optical flow. When you said you trimmed it and turned it off and back on , you were flying back in optical flow.
That is not exactly correct. When you push down on the left throttle trim and hold after a few seconds the TX LED blinks and it goes into the parameters menu. In this menu you can level the swash plate by adjusting the roll and pitch trim for a steady hover. The optical flow also switches off so that it does not impact the swash leveling. In this menu you can also adjust your pitch angles using the rudder trim.
@@Flight6677: You are right. That other dude seems to be a person, who always "knows" better. I over trimmed my heli once in air with this method. It works like you said in the video and your comment is also right: "The optical flow also switches off so that it does not impact the swash leveling." Thank you for sharing this video.🙂
